Abstract Background The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Methods Ten patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during 2 years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Results The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during 1 year follow-up showed no sign of failure. Conclusions The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.

Aim: Study aimed to test whether implants inserted in posterior mandible sites augmented with screw-guided bone regeneration (S-GBR) technique differ from implants placed in non-grafted sites regarding the success and survival rate. Materials and Methods: 20 edentulous patients (mean age 59.45 ± 15.220) were divided in a test group (S-GBR) (immediate implants placed simultaneously with grafting procedures) and control group (implants placed in naturally healed sites). Primary outcomes (implants success; implants survival) and secondary outcomes (clinical parameters of soft tissues: mPI; mGI; probing depth; keratinized mucosa; marginal-bone-level) were evaluated at 24-months follow-up. Results: Plaque levels were higher (p = 0.046) in S-GBR group (0.97 ± 0.882 mm) when compared with control (0.66 ± 0.695 mm). Keratinized mucosa width was higher in S-GBR group (4.13 ± 1.033 mm) than control (3.34 ± 0.821 mm) (p = 0.000) Probing depth (PD) width was higher in S-GBR group (3.50 ± 1.372 mm) than control (2.56 ± 1.332 mm) (p = 0.000). mGI was higher among implants placed in S-GBR group (0.90 ± 1.020 mm) than control (0.56 ± 0.794 mm) (p = 0.061). The difference between the average bone loss (MBL) for implants placed in grafted sites (Group S-GBR: 2.20 ± 1.867 mm) and for those placed in naturally healed sites (Group B: 1.09 ± 1.678 mm) was statistically significant (p = 0.000). The overall implant success rate after 24-month follow-up was 76.7% in S-GBR group and 90.6% in control group (p = 0.001). The survival rate after 24-month follow-up was 86.7% in S-GBR group and 93.8% in control group (p = 0.182). The reconstruction of the alveolar bone using S-GBR technique and immediate implant placement is a valid guided bone regeneration strategy for mandibular alveolar bone with severe horizontal resorption. The choice of S-GBR technique should be based on specific indications as implants placed in grafted sites recorded worse marginal success rate, survival rate and bone resorption than those placed in non-grafted sites.

Abstract Objective The aim of this study was to evaluate the performance of autotransplantation of a mature third molar to a fresh molar extraction socket using a 3D replica. Materials and Methods Ten patients underwent autotransplantation of teeth. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during one year following up, which were transplanted into fresh molar sockets by using a 3D replica, and GBR when it is necessary. Results The average extra-oral time of donor tooth had been shortened to 1.65 min. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Expect one patient feel slight sensitive when chewing with soft food at 4 weeks, and 3 points of probing depth deeper at different patients than 3mm and 1 points of probing depth deeper than 4mm at 4 weeks among them, and 1 points of probing depth deeper than 3mm at 5 weeks at the same patient. Conclusions The autotransplantation of teeth using 3D replica is an effective method which can reduce the extra-oral time of the donor teeth and the demand for the experience of a surgeon, and had a high success rate. Clinical Relevance The new 3D replica of donor tooth can make the surgery of tooth autotransplantation much easier, and improve it success rate.

ABSTRACT Objective: The objective of this review was to evaluate the outcomes of the treatment of peri-implant defects, using Guided Bone Regeneration. Methods: A literature search was performed based on the PICO methodology in the PubMed/Medline, SciELO, Lilacs electronic databases, CAPES periodicals and the Cochrane Library. We included studies using bovine mineral matrix, associated to a collagen membrane for the treatment of peri-implantitis by Guided Bone Regeneration. Results: Of 1,163 studies, 10 were included in this review after applying the evaluation criteria. A total of 269 implants were treated in 260 patients. The follow-up period ranged from 6 to 48 months. The studies evaluated outcome in terms of reduction in probing depth, gain of clinical attachment and healing of the bony defect. Due to the heterogeneity of the studies, it was not possible to perform meta-analysis. Conclusion: Treatment of peri-implant lesions with Guided Bone Regeneration is a viable modality of treatment, providing reduction in bleeding on probing, as well as gain of clinical attachment. Complete filling of the defect is, however, an unpredictable result.

Background:Giant cell arteritis (GCA) may affect the aorta and the large aortic branches and lead to dissections and aortic aneurysms. Tocilizumab (TCZ) treatment has the capacity to control aortic inflammation as has been demonstrated by CRP normalization and imaging data. However, limited data are available on the histopathological findings obtained from patients who underwent surgery because of aortic complications during TCZ treatment.Objectives:We report on 5 patients with aortitis who were treated with TCZ and developed aortic complications.Methods:We describe a retrospective case series of patients with GCA treated with TCZ, who presented in our clinic between 2011 and 2019. Three patients underwent surgery. Histopathologic examination was performed in specimen from all of them.Results:Five female patients were diagnosed with GCA (4/5) or Takaysu arteritis (1/5) involving the aorta, all them diagnosed by MR angiography and/or FDG PET CT scan. Three patients (one with aortic aneurysm, one with dissection) underwent surgery after having been treated with TCZ for seven weeks, nine months and four years, respectively. Imaging before surgery showed remission on MRI and/or PET-CT in all cases. At the time of surgery, all patients showed normalized CRP and ESR values. Histopathological evaluation of the aortic wall revealed infiltrates, consisting predominantly of CD3+CD4+ T cells. Enlargement of pre-existing aneuryms was observed in the other two patients 10 weeks and 4 months after discontinuation of TCZ, respectively. Both patients were not eligible for surgical intervention and died during follow-up.Conclusion:Our case series suggests that during treatment with TCZ, regular imaging is necessary in this patient population to detect development of structural changes such as aneurysms or dissections. Despite treatment, residual inflammation might persist which could contribute to eventual aortic complications.Disclosure of Interests:Andrea Rubbert-Roth Consultant of: Abbvie, BMS, Chugai, Pfizer, Roche, Janssen, Lilly, Sanofi, Amgen, Novartis, Peter Karl Bode: None declared, Thomas Langenegger: None declared, Claudia Pfofe: None declared, Thomas Neumann: None declared, Olaf Chan-Hi Kim: None declared, Johannes von Kempis Consultant of: Roche

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.
